Paul already answered it. Tnx Paul. My data is in a file and now I
have to take care to strip \t and \n from it.
Thanks

gurus:
I want to implement a sql-like sort-by on multiple keys. I've seen
many examples of just two keys.
I have a list like this
1 one 2
1 one 1
1 two 1
1 one 0
1 xx 0
result should be like this
1 four 2
1 one 0
1 one 1
1 one 2
1 xx 0
It moves right while keeping sorted order to the lef
